AI Technical Summary

Benefits of technology

The invention is about an improved chair or couch with motor-driven movable parts that can be assembled cost-effectively and quickly. The technical effects of the invention include the installation of the drive unit in a conventional manner, allowing for easy assembly, and the use of a connector cable that is routed outside the tube and attached to the motor and step-down transmission, creating sufficient movement for the adjustment slide. Additionally, a cable conduit is used to protect the cable and further aid in installation. Overall, this invention offers improved functionality and reliability at a reduced cost.

Problems solved by technology

Running the incoming cable within the chair is relatively costly and complex, and in particular takes quite some time.
This is costly in terms of the assembly and is associated with relatively high manufacturing costs.

Embodiment Construction

[0022]As seen in FIG. 1 a couch or chair 1 has a generally horizontal seat 2, an upright back 3 projecting up from a rear end of the seat 2, and a footrest 4 projecting down from a front end of the seat 2, all shown without upholstery or cushions for clarity of view. These parts 2, 3, and 4 are all slidable and / or pivotal on a frame 5 having a longitudinal floor beam 6 by a linkage 17.

[0023]In addition, an electric-motor-driven drive 7 is attached, for example, to the beam 6 and serves for operating the linkage 17. It has an electric drive motor 8 with a step-down transmission 9. A tube 10 extends from a housing 18 surrounding the motor 8 and transmission 9 and coaxially receives a drive element, such as, for example, a threaded spindle 16 that is operatively connected to the step-down transmission 9.

[0024]An adjustment slide 11 can move along the outer surface of the tube 10, with its longitudinal front-to-back position determined by the drive element 16, so that it connects this d...

Abstract

A couch or chair has a frame, a movable seat, a movable back, a movable footrest, and a linkage connected to the seat, back, and footrest to shift same between different positions on the frame. A drive has a motor, a transmission, a drive housing holding the motor and transmission and secured to the frame underneath the seat, and a rigid tube having a front end fixed to the housing and a rear end. A mounting bracket fixed to the rear end of the tube is secured to the frame, and a drive element in the tube is connected to the transmission. A slide on the tube between the ends thereof engages the drive element and is connected to the linkage to shift the seat, back, and footrest. A cable is connected to the motor, extends rearward along the tube past the bracket, and carries a plug.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a piece of adjustable seating furniture. More particularly this invention concerns a chair or couch with motor-driven movable parts.BACKGROUND OF THE INVENTION[0002]The invention relates to a piece of seating furniture, that is a couch or chair, with parts that are adjustable by an electric motor, and that specifically include at least one seat and / or back and / or footrest. The piece of furniture has a frame normally comprised of two vertical end members or plates interconnected by front and back longitudinal beams on which parts of the adjustment mechanism of the adjustable parts are pivotally linked or attached.[0003]A drive having an electric motor is attached to parts of the adjustment mechanism and also has a step-down transmission as well as a tube that projects from the motor and transmission and that surrounds a drive element, in particular, a threaded drive spindle that is operatively connected to the step-down tra...
